Python Properties
Python properties are a built-in feature that allows developers to define getter, setter, and deleter methods for class attributes, enabling controlled access and modification while maintaining a simple attribute-like interface. They use the @property decorator and associated methods to implement computed attributes, validation, or side effects without changing the public API. This mechanism supports encapsulation and data integrity in object-oriented Python programming.
Developers should use Python properties when they need to add logic (like validation, computation, or side effects) to attribute access while keeping the interface simple for users, such as ensuring a value is within a valid range or lazily computing a derived attribute. They are essential for maintaining backward compatibility when refactoring internal implementations, as they allow changing how an attribute is stored without affecting client code that accesses it as a plain attribute.
